To celebrate the holidays, AndyMark will be closed with no orders shipping on the following days:- Christmas Holiday: Friday, December 22nd - Monday December 25th- New Year's Holiday: Friday, December 29th - Monday, January 1st

All AndyMark gearboxes require grease for proper operation and long life. We suggest using our red tacky grease,
am-2768. We also encourage that the user powers the gearbox continuously for 30 minutes without grease to allow the gear teeth to wear in. While we do design with short run times in mind, this 'run in' period for smooth gearbox operation, is recommended. Once this is completed, thoroughly grease the gear teeth periodically to ensure smooth operation.

Product Overview: This 20-inch-long Nano Tube houses two complete gearboxes that drive 3 output shafts. This features the same gearing and shafts as the Nano with 500 Key Shaft.This gearbox accepts two 2.5 inch CIM Motors. Hardware is included for attaching two of these motors.
With two CIM motors installed all three shafts are powered by both the motors.

This product is intended to be used as a complete drive module for the side of a 6-wheel-drive robot. The center shaft is slightly lower than the two outer shafts for better turning. A second tube is to be used on the opposite side of the robot in order to make the complete drive chassis, be sure the middle wheel is lower on both sides. This same Nano Tube could be used for a 4-wheel-drive robot by removing the center shaft.

I currently use the Nano Tube Chassis as the primary platform for all of the "big" robotic projects in our robotics class. The pre-assembled platform allows my students to spend more time designing, researching, and building the other mechanisms associated with each assignment.
